11115 invention relates to a vibrator attachment for material Spreaders. 1

An object of this invention is to provide a vibrator structure which isconstructedas a separate unit and adapted for mounting on a hopper or truck body so as to'vibratethe body in order that the sand or other material in the body will be evenly and quickly discharged onto theground orroad. i

Another object of this invention-is to provide a. pair of supports for mounting on a truck chassis and body one support'for supporting a power member and the other for supporting the vibrator, so that each one of a series of trucks may be provided with the pair of supports, and the power member with the vibrator may be removably mounted on any one of the trucks or quickly transferred from one truck to another.

A further object of this invention is to provide a vibrator structure including a power member,

a vibrator, a detachable mounting for the vibrator and a flexible shaft between the power-mem her and the vibrator so that the latter'-mayb mounted at a point closely adjacent thepointj of discharge of the material from the truck'body;

To the foregoing objects, and others which may hereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts, as Willbe inorespecifically referred to and illustrated in the accompanying drawings, but it is to be understood that changes; variations, and modifications may be resorted to which fall within the scope of the invention as claimed.

Referring to the drawings, and first to Figures 1 to 5'inc1usive, .the numeral l0 designates generally a conventional truck body which is formed at the rear thereof with a material discharging gate H; .'In order to provide a meanswhereby the material in the truck body It may beevenly distributed or discharged atthe time the forward endxof the body i0 is raised relative to the chassis I2, I have provided a vibrator means which includes a power member i4-of conventional con struction in the form of an internal combustion engine or the like. The power member I4 is supported from the forward end of the chassis l2 by means of a supporting structure or bracket which includes a tubular member i5 which is welded or otherwise firmly secured to the side of the chassis frame l2 and projects laterally therefrom; The tubular member i5 is adapted to "have removably mounted therein atubular member ifi which is securedin the tubular mem ber'jl5,'the latter constituting a socket by means ofra rem'ovable securing pin i1, The tubular member [6 has fixed thereto and at right-angles tof'theflength 'thereof' an elongated rod I Bland ar ectangular framelil is fixed at its upper end tothetubular member 16 and also to the rod l8.

The rectangular member i9 includes a bottom member or plat'form 20 on which the power member L4 may be firmly secured]; One vertical side 2 ij o f 'the'frame I9 may beforjm'ed with an opening 22 throug which an elongatedfiexible 'sha'ftf23 isadapted to be extended. The flexible shaft 23 is extended rearwardly to a position beneath the end 'g ate structure H and is connected at itsrjar end to a vibrator member generally designated as '25. H The vibrator member 25 includes a housing 24 which is formed of a cylindrical body 26 hav ing end plates or heads 21 and 28 secured thereto and held against the ends of the cylindrical body 26 by securing bolts 29. The end plates or heads 2'! and 28 are secured by fastening members3il to angle members 3| which are fixed to a base plate 32. The housing 24 has rotatably mounted therein an elongated eccentric member or weight 33 having aligned studs 34 and 35 at the opposite ends thereof which are journalled in anti-friction bearings 36 and 3! disposedwithin the cyline drical member 26. The stud 35 extends outward,- ly into abushing 38 carried by the head plate 28 and the stud 35 which is formed with a, reduced extension 39; is provided with a polygonalsocket 46 within which the terminal end 4| of the flexible shaft is adapted to removably engage.

The flexible shaft or member '23 includes an outer sheath 42 having fixed to one end thereof a cap 43 which is adapted to be threaded onto the bushing 38. The base plate 32 has fixed to the upper side thereof a pair of lengthwise extending angle members 44 having parallel sides 45 which are spaced apart and between which a supporting bar or plate 46 is adapted to engage.

The bar or plate 46 includes an upper base plate 41 which may be secured by fastening memvigorously vibrated so that the material such as bers 48 or by welding to the bottom side of the 7 end gate or truck structure. The angle'members 44 are removably secured to the plate 46 by means of one [bolt 49 engaging through the anglemem- "sand or other fine material will be evenly dischargedfrom the rear of the truck body. As one example, this device has been designed for attachment to trucks used in sanding roads either bers 44 and the plate 46 and also by a second bolt I 50 whichengages in an obtusely inclined slot 5|- which is formed in the plate 46 spaced from the bolt 49. The provision of the angled slot 5| facilitates the mounting of thevibrator'structure on the plate 46 as bolt 50 may be moved upwardly into the slot 5| and the vibratorlstructure then pivoted or swung upwardly. until bolt 49 can be extended through the vertical sides of the angle members 44. Preferably, one of the angle members a is provided with longitudinally extending spaced parallel bars 52 between which the heads of the bolts 49 and are adapted to engage so that these bolts will be firmly locked against rotation. It will be understood that the vibrator; structure is under extreme vibration and without some extra provision being made the fastening membersfor the vibrato structure might readily break loose. J,;-Referring now to Figures-6 to 9 inclusive, ther is disclosed a modification of this invention which includes a vibrator housing 53 which is formed of a cylindrical body 54 openat one end and closed at the other end by means of an endcwall '55;- ,7 The housing 53 has secured thereto a pair of.- angle members or brackets 56 which are adapted to be secured as by. fastening members 51: to thelower side of the truck body or end gate. The housing 53. has -removablymounte d therein an elongated tubular body 58 constituting the inner housing for the vibrator and the body 58 is provided atone lend with an-end wall 59.

lAnelongated eccentric weight member 60 is ror tatably disposed within the body or housing 58 being formed with aligned studs 6| and 62 at theopposite ends thereof which are journalled in antifrictionbearings 63 and Y64, respectively. A

cap or plug 65 is threaded into the inner end of the housing or member '58 and bears against the adjacent anti-friction bearing 64. The stud 62 extends through the plug or bushing 65 and is formed with a polygonal socket 66 within which the end 61 of the flexible vibrator shaft 68' is adapted to removably engage. The shaft 68 has disposed thereabout a flexible sheath 69 and a cap I6 is carried by the outer end of the sheath 69 and is threaded on the plug or bushing 65.

In the use and operation of this device where a series of trucks are owned by a company or the like, each truck may have mounted thereon a vibrator supporting member 46 at the rear of the truck and preferably adjacent the end gate structure as shown in Figure 1. Each truck will also have mounted on the chassis the power member supporting socket 15. The vibrator structure may be secured to or mounted on a selected truck, the supporting bar or tube 16 being inserted into the socket l5, The flexible shaft 23 may if deto-dischargev the sand onto the icy roads or to discharge the sand evenly onto the topof tarred or otherwise treated roads.

The structure shown in Figures 6 to 9 inclusivez willr operate in 'the same ;manner as that shown in Figures 1 to 5. An'advantage of the structure shown in Figures 6 to 9 inclusive is that no tools are needed to mount the vibrator member-.58 within the tubular housing 54. The vibrator member 58 may be frictionally held withinthe outer housing 5.4; or if desired, suitable means may be provided at the open end of the housing 54 to hold the inner vibrator member against the endwise movement.
